Check Digit Verification of cas no

The CAS Registry Mumber 20278-59-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,2,7 and 8 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 20278-59:
(7*2)+(6*0)+(5*2)+(4*7)+(3*8)+(2*5)+(1*9)=95
95 % 10 = 5
So 20278-59-5 is a valid CAS Registry Number.

THE NUCLEOPHILIC AROMATIC PHOTOSUBSTITUTIONS OF 4,5-DINITROVERATROLE WITH AMINES. PHOTOREDUCTIONS OF AROMATIC DINITROCOMPOUNDS

Marquet, Jorge,Moreno-Manas, Marcial,Vallribera, Adelina,Virgili, Albert,Bertran, Joan,et al.

, p. 351 - 360 (2007/10/02)

4,5-Dinitroveratrole is effectively photosubstituted by amines with relatively high ionization potential such as methylamine, n-butylamine and ethyl glycinate, but is mainly photoreduced when amines with relatively low ionization potential, such as dimethyl or trimethylamine are used.The photoreduction of several aromatic dinitrocompounds by triethylamine gives nitroanilines.A mechanistic scheme is proposed embracing our photosubstitutions and photoreductions, based on our experimental results and on MINDO/3 calculations of the ground states and the more likely intermediates.
